I took the plan b the next day . Todays Thursday and nothing has happened

Hi Elizabeth, if you took the morning after pill as directed you should be ok. All you can do is wait until your period is due. If you get it its all good. Or if its late take a test. but try not to stress. It should be fine. And at risk of sounding like a bossy adult, always use condoms. you don't want to be going through this stress every time you have sex. All the best
